Abstract (en)

[origin: EP0709758A2] An electrical heating system (10) has a resistance heater (11) that is controlled by a charge regulator (20) based around a regulating amplifier circuit (22). Actual temperature is fed back from a sensor (12). The power connection to the heater is provided by a Triac power switching stage (21). The power range of the heater is defined for specific requirements and the rating is fixed at the post of installation. The adjustment of the regulator to suit these conditions is provided by valves entered into an EPROM memory (26) from a coding module (27).
